Title: Magnetic tunnel element and its production
Inventor: SUGAWARA JUNICHI
IPC: G11B5/31
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To permit the maintenance of stable tunnel current by providing the magnetic tunnel element with a tunnel barrier layer which is formed on a first material layer and is formed by oxidizing a metallic film by the oxygen plasma formed by a high-frequency induction coupling system and a second magnetic layer which is formed on this tunnel barrier layer. SOLUTION: The first magnetic layer is formed of a two-layered structure formed by laminating an NiFe layer 7 and a Co layer 8, successively from a first electrode side. The second magnetic electrode layer is formed of a two- layered structure formed by laminating a Co layer 9 and an IrMn layer 10 successively from the tunnel barrier layer side. The NiFe layer 7 is a magnetized free film which has low coercive force and changes the magnetization direction thereof with respect to an external magnetic field. The magnetic reluctance of a magnetic tunnel element is made larger by disposing the Co layer 8 and the Co layer 9 at the boundary of the NiFe layer 7 and the tunnel barrier layer. The tunnel barrier layer is formed by oxidizing the metallic films of Al, Gd, Hf, Fe, etc., by the oxygen plasma formed by the high-frequency induction coupling system.

Title: Abnormal state restoration system for local network system
Inventor: MASUO YASUHISA
IPC: H04L12/42
Filed: 1992-10-01
Abstract: PURPOSE:To shorten the restoration time of an abnormal state by judging the abnormal state by a monitoring station when no transmission of a valid frame is present from a station from which a token is received when a non- communication state from the station is continued for a fixed time and omitting the pertinent station from a network map. CONSTITUTION:At the monitoring station 11, token monitoring is performed by receiving the token to be broadcasted and the station holding the token at the present is recognized. In the fixed time corresponding to the time for transmitting the token from the recognized station to the next station, when the monitoring station 11 detects that the non-communication state is continued, it is discriminated that a network failure is generated and the token is retransmitted to the pertinent station by the monitoring station 11. Thereafter, when the valid frame is received, the monitoring station 11 considers that the delivery of the token is succeeded and returns to a token monitoring state.

Title: String fastener
Inventor: FUKUYA SHIGERU
IPC: A44B13/00
Filed: 1994-10-03
Abstract: PURPOSE: To provide a string fastener capable of simply and quickly fastening and loosening a string by combining a guide part of the string and a wedge in a chevron shape by means of connecting rod. CONSTITUTION: A reverse trapezoid shaped wedge 3 and a guide part 4 of a string 1 are tied with a connection rod 5 and the string 1 is inserted through between the wedge 3 and the guide part 4 of the string 1. When the string 1 is drawn toward the directions of arrow marks C and D, the wedge 3 is moved toward the direction of arrow mark F by the friction force with the string 1 causing the friction force not to be larger. In reverse, however, when the string 1 is drawn toward the arrow marks A and B, the wedge 3 is moved toward the arrow mark F by the friction force with the string 1 causing to press the string 1 strongly to the guide part 4 of the string 1. Consequently, the more the string is drawn toward the directions of the arrow marks A and B directions, the stronger the friction force with the wedge 3 becomes, and the string 1 is not moved toward the directions of arrow marks A and B. This string fastener can be made to be device capable of easily fastening and loosening the string 1 by harmonizing three points of the angle of the chevron shape of the connecting rod 5, the position on the guide part 4 to pinch the string 1 and the friction resistance of the wedge 3 in contact with the string 1.
